7 RNEUMATIC CARRIER.

SPECIFICATION forming part of Letters Patent No. 760,680, dated May 24, 1904.

' Application filed November 14,1903. Serial No. 181,141. (No model.)

To all whom, t may con/cern:y

Be it known that I, CHARLES H. BURTON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic Carriers, of which the following is a specification.

My invention relates to carriers for pneumatic-despatch tubes, and` especially to the type of carriers shown in Letters Patent issued to me April 21, 1903, No. 726,022.

My invention consists of certain novel features hereinafter described,` and particularly pointed out in the claims. v

In the accompanying drawings, which illustrate a construction embodying my invention,

Figure l is an enol view of oneend of the carrier. Fig. 2 is a side View of one end of tional view hereinafter described.

Like letters of reference refer to like parts throughout the several views.

G and H of two of the shafts Cthere is lo-v cated the cast-steel 'plug K, which is forced down into place between said ends-G and H,

. and its lower end K is held firmly iny place by the pin K2. Said plug K has an inner eXtension K3, which fits down between two adjacent bearings B B, and thereby holds the plug against lateral movement. With -the'parts in the position described and shown theV shaftsk are securely fastened in place and are pre-Y vented from dropping into the line. While I have shown this arrangement on one end of the carrier, yet it-will be understood that a similar arrangement is providedon the other ond. 4

Fig. 3 is a cross-sectional viewV on the line X X, Fig. 2. Fig. i is a detail sec- Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a carrier adapted lfor transit in a pneumatic-despatch tube, the combination with the body of the-carrier of a series of supportingwheels mounted thereon and at each end, aXleshafts for said wheels, bearings for said shafts, and a device between the ends of two adjacent shafts for holding said shafts in position.

2. In a carrier adapted for transit in a pneumatic-despatch tube, the combination with the body of the carrier of a series of supportingwheels mountedthereon and at each end, axleshafts for said wheels, bearings for said shafts, an interlocking joint between said shafts, and a device between the ends of two adjacent shaftsfor holding said shafts in position.

3, In a carrier adapted for transit in a pneumatic-despatch tube, the combination with the body of the carrier of a series of supportingwheels mounted thereon and at each end, axleshafts for said wheels, bearings for said shafts, a device between the ends of two adjacent shafts for holding said shafts in position, and means for locking said device to the body vof the carrier to hold it in position.

4L. In a carrier adapted for transit in a pneumatic-despatch tube, the combination with the body of the carrier of a series of supportingwheels mounted thereon and at, each end, aXleshafts for said wheels, bearings for said shafts, a device between the ends of two adjacent shafts for holding said shafts in position, and

means for preventing the lateral movement of' said device. 5. In a carrier adapted for transit in a pneumatic-despatch tube, the combination with the body of the carrier of a series of supportingwheels mounted thereon and at each end, axleshafts for said wheels, bearings for said shafts, a device between the ends of two adjacent shafts for holding said shafts in position, means for locking said device to the body of the carrier to yhold it in position, and means for preventing the lateral movement of said device.

6. In a carrier adapted for transit in :t pneumatie-despatch tube, the combination with the body of the carrier of a series of supportingwheels mounted thereon and at each end, axleend of said plug for holding it against longi* tudinztl movement.

In testimony whereof l have signed my naine to this specification, in the presence oi two subscribing witnesses, this 12th dey oi November, A. D. 1903.

CHARLES H. BURTON.
